Two perceptual features can be compared faster if they are part of a common object. This same object advantage has been demonstrated amongst others by Behrmann et al. (1998). However, the stimuli used by Behrmann et al. are either confounded with the orientation of the to be judged details (X-shaped stimuli, Exp. 1) or the perceived objecthood of the occluded stimulus is vastly reduced (V-shaped stimuli). In Experiment 1, we avoided these issues by implementing slightly curved X-shaped stimuli that remove the confounding with the orientation of the to be judged details and at the same time create a strong impression of two superimposed objects. In Experiment 1 we found that the target identity inverts the same object advantage, replicating a finding by Chen and Huang (2015). However, in the stimuli utilized in Experiment 1 target identity is still confounded with symmetry (Saiki, 2000). In Experiment 2, we avoided this confound by replicating this experiment with random superimposed objects thereby minimizing the symmetry of the stimulus configuration. As a result, we found the same object advantage both for identical and different stimuli. Moreover, the same object advantage does not depend on whether the object is shown in front of or occluded by the irrelevant object confirming a central finding of the Behrmann et al. (1998) study.
